Zolpidem (Ambien): Uses, Dosage, Side Effects, Addiction, Warnings

What is zolpidem tartrate?

Zolpidem tartrate is a sedative, also called a hypnotic. It affects chemicals in the brain that may be unbalanced in people with sleep problems (insomnia). Zolpidem is used to treat insomnia. The immediate-release forms are Ambien, Intermezzo, Edluar, and Zolpimist, which are used to help you fall asleep.

The extended-release form of zolpidem has a first layer that dissolves quickly to help you fall asleep and a second layer that dissolves slowly to help you stay asleep. Zolpidem can help with difficulty falling asleep, frequent wake-ups during the night, or early morning awakenings. Zolpidem should usually not be taken for more than 7 to 10 consecutive days. It should only be used if disturbed sleep causes problems functioning during the day.

How Does Zolpidem Work?

Zolpidem acts as a central nervous system (CNS) depressant by increasing the levels of gamma-aminobutyric acid (GABA) in the brain. This chemical is responsible for slowing activity in the brain to allow a person to fall asleep more easily. Individuals suffering from insomnia are often unable to calm the brain and body enough to fall asleep, so taking Zolpidem can help a person relax and increase feelings of calm.

How should I use Zolpidem?

The recommended adult dose of zolpidem is 5 mg for women and 5 mg to 10 mg for men. Women have higher levels of zolpidem in the blood than men when given the same dose. It also takes longer for women for the medication to be cleared from the body.

Zolpidem should be taken just before bedtime when required to help with sleep disturbances. Zolpidem may be habit-forming and should be taken exactly as prescribed by your doctor. You should not typically use zolpidem for more than 7 to 10 consecutive days.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Do not take Zolpidem with food or immediately after a meal. Food slows down the speed at which the medication works, increasing the length of time before the onset of sleep.

If you have been taking this medication regularly for an extended period of time, do not stop taking it suddenly without talking with your doctor.

It is important that this medication be taken exactly as prescribed by your doctor. If you forget to take your tablet at bedtime, do not take it at any other time or in the middle of the night. Do not take this medication when a full night’s sleep (7 to 8 hours) is not possible (i.e., after waking in the middle of the night) or before you would need to be active and functional. Impaired judgment and memory lapses may occur in such situations. Your body needs time to process and get rid of the medication.

Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

How Long Does Zolpidem Stay in Your System?

Zolpidem’s half-life is between two and three hours -which is very short. The average half-life of the drug is around 2.6 hours in healthy adults. So, after taking a dose of zolpidem, the body will have eliminated half of it within two-and-a-half hours, or so. Full elimination of zolpidem can take anywhere from 11 hours to 16.5 hours. The average person will have cleared zolpidem from their system within 14 hours after taking it. Even after the parent drug is eliminated from the system, metabolites may linger in the body. Longer-lasting metabolites can cause zolpidem to show up on drug tests beyond 14 hours. Some evidence suggests zolpidem may show up in a urine drug screen for one to three days.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breastfeeding, and any other significant facts about your health. These factors may affect how you should use this medication:

Alcohol use: The use of zolpidem after consuming alcohol increases the risk of severe side effects such as breathing difficulty and performing activities while not being aware or awake. Alcohol should not be consumed if you are taking zolpidem.

Allergic reaction: In rare cases, people have developed a serious allergic reaction to medications like Zolpidem involving swelling of the tongue, glottis, or larynx. Some people have had shortness of breath, nausea, vomiting, or throat closing.

Other signs of an allergic reaction include a severe rash, hives, swollen face or throat, or difficulty breathing. If you experience any of these symptoms after taking zolpidem, seek immediate medical attention.

Behavior changes: This medication may cause agitated or aggressive behavior. If you experience these symptoms or any other behavior change while taking this medication, contact your doctor immediately.

Family members or caregivers of people who are taking this medication should contact the person’s doctor immediately if they notice unusual behavior changes.

Breathing problems: Zolpidem can suppress breathing. If you are at risk for breathing difficulties, such as asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Confusion: Zolpidem affects mental efficiency (e.g., concentration, attention, and vigilance). The risk of confusion is greater for seniors and those with brain damage.

Dependence and withdrawal: Physical dependence, psychological dependence, and abuse have occurred with the use of Zolpidem. If you have a history of past or current substance use problems, you may be at greater risk of developing abuse or addiction while taking this medication.

Withdrawal symptoms have been observed after stopping the medication suddenly (after having taken it regularly over a period of time). These symptoms include:

•          abdominal cramps

•          anxiety

•          diarrhea

•          fatigue

•          flushing

•          headache

•          irritability

•          memory impairment

•          nausea

•          nervousness

•          restlessness

•          seizures

•          sleep problems such as rebound insomnia

•          sweating

•          tension

•          tremors

•          vomiting

If you have been taking this medication for longer than 10 days, discuss with your doctor the best way to stop Zolpidem.

Depression: Medications used for sleep disturbances have been known to cause mood swings and symptoms of depression. Zolpidem may worsen symptoms of depression, including thoughts of suicide or wanting to harm others.

If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, or decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Drowsiness/reduced alertness: Zolpidem can cause excessive daytime drowsiness and decreased mental alertness. Do not drive, operate machinery, or perform other dangerous tasks until you know how this medication affects you.

Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

Memory disturbance: Although rare, amnesia of varying severity has been reported following normal doses of medications like Zolpidem. This is an unpredictable effect of the medication. If you experience any memory problems while taking this medication, contact your doctor.

Performing activities while not fully awake: People taking Zolpidem may perform activities such as sleepwalking, driving, preparing and eating food, and making phone calls while not fully awake and are unaware of their actions. The next morning, they may not remember what happened. This may be more likely to occur if you use alcohol or other sedative medications. If you discover this has happened to you, contact your doctor immediately.

Family members or caregivers of people who are taking this medication should contact the person’s doctor immediately if they notice any of these unusual behaviors.

Rebound insomnia: As with other medications used to aid in sleeping, you may experience a temporary return of your sleeping difficulties when zolpidem is stopped.

Pregnancy: The use of Zolpidem during pregnancy has not been studied. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breastfeeding mother and are taking Zolpidem, it may affect your baby. Talk to your doctor about whether you should continue breastfeeding.

Children: The safety and effectiveness of zolpidem have not been established for use by children and adolescents less than 18 years of age.

Seniors: People over 65 years of age are more likely to experience dose-related side effects of zolpidem, such as drowsiness, dizziness, or impaired coordination. Lower doses of Zolpidem are recommended for seniors.
